Browse by date

You can also browse recently added records clicking the Browse by date button, which will display a drop down list of time periods.

For example, selecting the option ‘Last week’ will display all records added in the previous seven days.

Advanced search

The advanced search allows a tailored search of many Natural Product Updates fields, including author name, bibliographic data, source organism, taxonomic names, biological activities and compound class, and can be accessed by clicking the Advanced search button in the Search box on the homepage.

Free text

The user can toggle between a free text search of the article title only or article title and abstract using the radio buttons.

Article type

Natural Product Updates uses predefined article types to classify articles. Currently only the article type ‘Reviews’ is available.

To add an article type to your search, select it from the drop-down list. To see suggested article types, begin typing in the box and matches will appear in the list below. Only article types present in the list can be added.

To remove a selected article type from the search, click the X next to the article type in the search box.

Journal

To add a journal name, select it from the drop-down list. To see suggested journal names, begin typing in the box and matches will appear in the list below. Please note that Natural Product Updates uses the CAS Source Index (CASSI) abbreviations for journal names.

Journal

To add an additional journal name, click in the journal name box and repeat the process. When searching with multiple journal names, an OR search will be performed, e.g. a search for ‘Journal: J. Nat. Prod.; Journal: Nat. Prod. Rep.’ will return all records related to articles in J. Nat. Prod. or Nat. Prod. Rep.

To remove a selected journal name from the search, click the X next to the word in the search box.

Journal name remove

Author

Author names can be added using family name and/or given name.

To added additional author names, click the Add author link. When searching with multiple author names, an AND search will be performed, e.g. a search for ‘Author: Smith; Author: Jones’ will return all records related to articles that have both Smith and Jones as authors.

To remove author names, delete the text from the box.

Source

The required source organism can be selected from the drop down box. Suggested organisms can be viewed by typing the first few letters into the box and matches can be selected from the box below. Only source organisms in the list can be added to the search.

To add an additional organism, repeat the process above. When searching with multiple organisms, an AND search will be performed, e.g. searching for ‘algae’ and ‘bacteria’ will return records that list their source organisms as both algae and bacteria.

To remove a selected organism from the search, click the X next to the word in the search box.

Compound class

Natural products are divided into several general classes of compounds, which can be searched using the compound class drop-down box. Only classes on the list can be searched. Suggested classes can be seen by typing the first few letters of the class you are interested in.

More than one class can be searched by repeating the class selection above. Multiple classes will be searched in an AND fashion, e.g. a search for ‘abietanes’ and ‘diterpenoids’ will only return records that contain both classes.

To remove a selected compound class from the search, click the X next to the word in the search box.

Genus and species

Both genus and species are listed for source organisms (if provided in the original article). Genus and species can be searched independently or in tandem to find the species of interest.

To search, select the required genus or species name from the drop-down box. Suggested names can be found by typing the first few letters into the box of interest. The genus and species boxes are linked, so that selecting a genus automatically limits the available species options to those that have been reported and vice versa.

The species ‘sp.’ is listed for organisms that were explicitly of unknown species in their original article. A search for ‘Streptomyces sp.’ will only return articles where both genus and species terms are present. To search all Streptomyces species, select the genus only.

To remove a genus or species name from the search, click the X next to the word in the search box.

Biological activity

Articles that report a biological activity can be searched by selecting the required activity from the drop-down box. To view suggestions, type the first few letters and matches will be displayed in the box below.

Multiple biological activities can be selected by adding additional terms from the drop-down box. Terms are searched in an AND fashion, e.g. a search for ‘anti-HIV compounds’ and ‘antioxidants’ will only return articles where both activities have been listed.

To remove a selected biological activity from the search, click the X next to the word in the search box.

Date added

Records can be searched by the date that they were added to Natural Product Updates. Please note that this date is different to the article publication date. Dates can be defined as ‘From’, ‘To’ or both.

Datepicker

For example, a search for ‘From: 2015-01-19’ will return all records added since 19 January 2015; a search for ‘From: 2015-01-19; To: 2015-01-23’ will return all records added between 19 and 23 January 2015, inclusive.

Multiple search parameters

Important: When performing a search using multiple parameters, the individual queries are combined in an additive manner, which means that you will only obtain results where there are records that match all criteria.

For example, a search for ‘Article type: reviews; Author: Smith’ will return results for records with Article type: reviews AND Author: Smith.

Once you have entered your search parameters, click Search to run the required search. The form can be cleared at any time by clicking the Clear button at the bottom of the search page.

Viewing search results

Whenever you perform a search a new page will be displayed. This results page will show the number of results that were obtained and the search parameters that you specified, followed by the records returned by the search. The first 12 records will be displayed automatically; further records can be displayed by clicking the Show more bar at the bottom of the list.

Each record gives bibliographic details, natural products and a representative structure. The DOI link will take you to the original publication at the publisher’s site.

  • The index terms for a record, including source organism, taxonomic names, biological activity and compound class can be viewed by clicking on the Show details link.
  • The abstract can be displayed by expanding the record using the Show abstract link.
  • The representative structure can be downloaded in .tif and .cdx formats.
  • Citations can be downloaded by selecting the required records and choosing the reference manager format required from the drop-down box at the top of the results list, before clicking Go to export.

The results list can be filtered by journal title, source organism, compound class and biological activity by clicking on the appropriate name in the boxes in the right hand column. Expanding the boxes will give more filter names. Filters that have been applied can be seen in the boxes at the right of the results page and in the search criteria box. To remove a filter, click the X next to the filter name in either location.
